Abstract: 367,354. Printing tickets. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 64, Heathwood Gardens, Charlton, both in London. Nov. 14, 1930, No. 34321. [Class 100 (iv).] Relay type-wheel actions.-In a ticket-printing and issuing machine, a master member which may bear type on a portion of its periphery is initially clutched to a common driving-source, a number of auxiliary printing-wheels being independently clutched thereto by individual clutching devices when the printing portion of the master member is in alignment with the appropriate type on the auxiliary members. The severing of the ticket, inking of the type, printing, and delivery are successively performed, near the end of the first revolution of the master member, which then makes another rotation to normal during which the auxiliary members are declutched at their normal positions. The invention is described applied to a totalizator machine for issuing betting tickets bearing the race number, runner number, class of bet " win," " place," or " each way," and the stake value, as well as any desired fixed data. The master member (wheel) M, Figs. 2, 4, and 7, is fixed to the main driving-shaft MD concentric with which are rotatably mounted sleeve shafts TR, TCT, TCU, TB, TS, Fig. 4, carrying, respectively the type-wheels R, CT, CU, B, S corresponding to the race number, tens and units digits of the runner number, class of bet, and stake value ; and at their opposite ends spur-wheels SR, SCT, SCU, SB, SS, each of which engages a spur-wheel SC having twelve teeth cl2, forming the free part of an individual clutch assembly CUT. The driving-part comprises a lay shaft LS, Fig. 4, driven from shaft MD through gearing SM, SL and bearing a portion cl1 the teeth t of which may engage teeth cl2 in one of twelve positions. When the operating magnet EM is energized the loose collar C forces teeth t, cl2 into engagement, the tooth dt of a dog D integral with the sleeve shaft carrying the spur wheel SC thereupon riding on the upper surface of a fixed back stop BA and preventing declutching, until shaft LS has completed a revolution when tooth dt will fall under the action of a spring SPR and lock in the notch d. Secured to the shaft MD, Fig. 2, is a further spur-wheel SW gearing with a half-speed wheel HS, fixed to a shaft SH bearing a knife cam KC, Figs. 2 and 6, which rocks a member CMB about pivot P to lift a bowed knife blade BB, pivoted at one end and sprung at SRR, past the fixed blade BT. The ticket strip is fed between a driven roller FR, Fig. 6, and a spring-pressed roller RO, the spur-wheel PS, driving the roller FR, meshing with a nearly semicircular toothed segment PF of the wheel HS.' To prevent jamming segment PF is spring-borne and pivoted to the wheel HS, so as to give slightly on meshing. The type N, Fig. 7 (fixed or standard data), occupies one-twelfth the periphery of wheel M and normally is in the position NO, Fig. 6. The race number types relating to races 1, 2 .. normally occupy respectively the segments 1, 2, 3 .. 9, 0, on the wheel R. The wheels CT, CU are similarly divided, the digits 2 . . 9, O occupying correspondingly numbered segments. The wheel B may bear on segments 1, 2, 3 the legends " win," " place," " each way," the remainder being blank, and the segments 1, 2 .. of wheel S may bear stake value type of 2/-, 3/- .. 10/-. Mounted also on the shaft MD is a wiper W, Figs. 2 and 11, in alignment 'with the segment NO and adapted to wipe over contacts 1, 2, 3 .. 9, O, IK, NO, Fig. 11, aligned with the corresponding segments. To set up a bet a runner key KCU, Fig. 11 (two keys if runner number is greater than nine), a class key KB, and a stake value key KSV are depressed, the race number selector RSE being manually set by depressing a key KR, its position being shown on a lamp indicator LP. Contacts r3 are thereby closed energizing the main clutch magnet CL which now rotates the main shaft MD, and with it the wiper W. When live contacts CS are encountered the EM clutch magnets EMR, EMCU, EMB, EMS corresponding thereto, energize, and the appropriate type which are clutched to the main wheel M with the type relating to the keys depressed in alignment with the segment NO. The ticket T1 is severed about the time type N .. passes through position 8, and passing through position 1K the part DP of inking cam 1C in alignment with type N, allows roller 1R, Fig. 7, to ink the type. Passing from position 1K to position NO the platen PP functions, the ticket T1 being printed and shot into a delivery shoot in the one operation. Delivery rollers IRO, DRO, Fig. 9, described later, may however be used. A little later the ticket strip is advanced by the wheel PS meshing with the segment PF. The wheel M now commences a second revolution, the main clutch being held while passing through the normal position by a self-locking relay in the circuit thereof, de-energized after this position is passed by a suitable cam on shaft SH, after which it is held mechanically, falling off at the end of the second revolution of wheel M. The clutch magnets are de-energized at the end of the first rotation of wheel M but are still held mechanically by the teeth d, Fig. 4, riding on the respective back stops BA. When they reach their normal positions the teeth d fall into the notches dt declutching the corresponding type-wheels. To distinguish further between class tickets, for example, win tickets may have printed thereon a coloured mark such as a red cross. This may be effected by a further printing roller RPR, Fig. 9, co-operating with an ink bath RIB and inking rollers RRO, RSR, situated at the exit point of the ticket and operated electromagnetically by the " win " key. The roller RPR is adapted to plunge between two coaxially mounted rollers IRO which co-operate with a roller DRO driven from a lay shaft LS to advance and eject the ticket. The machine is provided with local counters REG, Fig. 11, one for each stake value, as well as being connected to the central totalizator, and contacts may be fitted adapted to lock the machine against operation when (1) the ticket-feeding mechanism does not advance the strip, (2) the ticket strip roll is used up, and (3) when the casing of the machine is removed. Specifications 357,616 and 367,488, [both in Group XIX], are referred to. According to the Provisional Specification the contact CS corresponding to the position NO of the main type wheel M, is connected to a relay operated when the wiper passes thereover at the end of its first revolution to reset all the depressed bet keys, thereby de-energizing the corresponding clutch magnets. If several ticket machines are grouped together a common driving mechanism may be employed with a clutch mechanism for each machine. Means electrical and/or mechanical are mentioned for operating the main clutch. Hammer - impression arrangements.-The platen PP, Figs. 2, 6, and 7, is carried in a spring- mounted frame F, two cams PC on shaft SH acting on members ME, allowing the platen to force the severed ticket T1 against the type. Roller inking arrangements.-The inking device is carried in a pivoted sprung frame (not shown), an inking cam IC, Figs. 2 and 7, fixed to shaft MD permitting the inking roller IR to contact with the type-wheels for the portion DP, Fig. 7, of a revolution. The ink bath IB has an extension ET contacting with a cam CA under the action of a spring SN and once per revolution of CA the free roller ROL (the ink supply to which may be varied by means of an adjustable roller RRR) contacts with a spreading roller SRO rotating with the cam CA. One of the lay shafts LS, Figs. 4 and 7a, drives through gearing SSW and SU an arm DO which engages and drives the crank CR fixed to roller SRO and cam CA, this loose coupling allowing the spreading roller SRO and the inking roller IR frictionally driven thereby to rotate rapidly, as indicated by the arrows, Fig. 7, when the roller IR contacts with the type N .. which is in alignment with the depression DP in the cam IR.
